Team Analysis

Pittsburgh Pirates

The Pirates have surged to a 4-1 record over their last five games, producing 5.0 runs per game, which signals a lineup finding rhythm at the perfect time. Bryan Reynolds has been central to their offensive stability, while Andrew McCutchen has provided timely production that elevates their scoring ceiling. On the road, despite a season-long struggle, their recent surge shows renewed confidence and a lineup capable of sustaining pressure in hostile environments.

Tommy Pham’s consistency adds another layer to the offense, giving the Pirates reliable depth in run creation. Their pitching staff has kept games under control, allowing the offense to win with efficiency rather than volume. With momentum firmly on their side and a recent scoring profile above five runs per contest, this team has the form and balance to extend its winning stretch in Boston.

  • Batting Average: 0.234
  • Total Runs Scored: 488
  • Home Runs: 98
  • OBP: 0.306
  • SLG: 0.352
  • OPS: 0.657
  • ERA: 3.91
  • WHIP: 1.21

Away Record: 22-46 • Home Record: 39-30
Last 5 Games: 4-1 (5.0 RPG)
Last 10 Games: 8-2 (5.1 RPG)


Boston Red Sox

The Red Sox are 3-2 over their last five, but their scoring has dipped to just 3.2 runs per game, indicating an offense that is not firing at full capacity. Trevor Story has been the most consistent run producer, but the supporting cast has not sustained rallies at the same pace. At home, they have been reliable overall, yet their recent offensive lull suggests vulnerability against a surging opponent.

Wilyer Abreu and Alex Bregman have provided occasional sparks, but the lack of consistent production points to why Boston’s recent contests have leaned toward lower totals. Their pitching staff remains solid, but the reduced scoring output limits their margin for error in tight games. With the Pirates entering on a hot streak, Boston’s current rhythm looks insufficient to overpower a confident visiting side.

  • Batting Average: 0.252
  • Total Runs Scored: 670
  • Home Runs: 164
  • OBP: 0.323
  • SLG: 0.425
  • OPS: 0.748
  • ERA: 3.66
  • WHIP: 1.28

Away Record: 34-35 • Home Record: 41-27
Last 5 Games: 3-2 (3.2 RPG)
Last 10 Games: 7-3 (4.1 RPG)

Boston Red Sox’s last 10 games have averaged 7.3 combined runs, with 4 games clearing the same number of 8.5.

Moneyline Betting Prediction

The Pirates’ 8-2 surge across their last 10 games, combined with back-to-back head-to-head wins at Fenway, makes them the sharper side. With Reynolds, McCutchen, and Pham anchoring a lineup producing over five runs per contest and Boston’s bats cooling, this matchup tilts decisively toward the visitors.

The Pittsburgh Pirates at +155 check enough boxes to be the value side.

Over/Under Prediction

In their last five, the Boston Red Sox have produced 3.2 RPG and the Pittsburgh Pirates 5.0. That output frames how this total sets up.

These teams are combining for 8.2 runs per game recently — below the posted total of 8.5. That points toward the Under 8.5.
